It represents the revegetation-monitoring component of the project and summarizes findings. This project has a 5-year annual monitoring requirement after the final planting (through 2004) to determine whether performance standards are met from the original plan. A revegetation project is zuccessful wher; after 3 years (2002), the areas designed for dense revegetation have 85% ground cover with less than l5oh of that cover comprised of weed species. Survivorship of tree and shrub species is expected to be 80o% or greater. Monitoring was conducted on July 8, 2002- 1.1 Project HistorT In l9g7 the City of Port Townsend constructed a stormwater retention pond from a Category III wetland. Water was directed towards this retention basin as part of the San Juan Street Improvement Project and via street runofffrom Cedar Street and Pacific Avenue after passing through bio-filtration swales. Re-vegetation occurred in 1998 and 1999 with over 200 trees, 400 shrubs, and 500 emergentlherbaceous natives introduced to a waste area that once consisted primarily of weedy species. The City of Port Townsend was awarded a Public Involvement and Education (PIE) grant from the Puget Sound Water Quality Action Team in 1998. As part of this grant a six-week training course was conducted; in exchange for the class students volunteered time towards the restoration project by planting, installing habitat features, and assisting in the ongoing maintenance of the site through 1999. As crty funding tightened and staffchanged the Froggy Bottoms Revegetation project lost its priority and maintenance was turned over to an already overloaded City Park staff. Minimal maintenance has been conducted since 2000. And although an irrigation system was installed in 1998, it was not monitored or maintained and was often not turned on until well into the dry summer. Weeding and mowing has been sporadic during the last 3 years. 1.1.1 Volunteers Through extensive volunteer efficrt (over 600 hours) from 1998 and 1999 the site has been re-vegetated with native trees, shrubs, and herbaceous species. In addition to divers&ng plant species, habitat structures were installed. During March 2Q02 avolunteer goup led by Ron Sikes planted an additional 200 small trees and shrubs. There are no plans for the maintenance of these additional plants. 1.1.2 Maintenance and lrrigation Maintenance of the site was conducted by volunteers in 1997 through 1999. Major weed removal and heavy mowing could not be expected of volunteers but the planted species were maintained. Resources Renewal lnc., Quilcene WA city mowing crews, city parks crew, and juvenile crews also removed Olr.rnpic Wetland Resources. Inc.

The irrigation system has not been activated since 2000 and will not be turned on this year since most of the planted species that remain are adapted to the site. A chronology of n aag({_,.s planiings, and maintenance of the site is included in the Appendix (Figure VII). Dwod g,dr:. ;V ,:h^ 1.1.3 Eydrology WJ*(;*-. (,pt^ The hydrology has fluctuated over the 5-year monitoring period. The driest year was 2001, overall site ,J01"i .- conditions were dry, no water was present in the lowJying areas. Established wetland tolerant ,'Jo"nfV' ' vegetation was stressed and dying and weedy species were spreading. Ponded water was present once lv again during the 200112002 winter and during this monitoring phase. Photographs from the previous reports reveal water levels. In 1998 there was a large pond, in 1999 the pond was smaller but standing water was still the major feature, in 2000 standing water was reduced to a ponded area near the water gauge. Throughout most of 2001 the valley floor was baked and cracked. During this season's monitoring the water levels were similar to 1999 water levels (Appendix: Figure VI Photopoint #6). The amount of hydrology depends entird on stormwater runoffand natural conditions (evaporation, sunny days) Many of the species chosen for the project prefer wet conditions. 2.0 Methodology 2.1 Project Goals and Objectives One of the primary goals of the Froggy Bottoms Revegetation Project is to use native plants to create a diverse habitat, which over time will encourage additional use by wildlife. Native vegetation was selected, g.riog priority to species that benefit wildlife and can withstand local climatic conditions. Long-range goals include enhancing open space and utilizing biofiltration as a creative solution to stormwater problems. Goals from original plan that have been met rn2002. l. Several species oftrees and shrubs are established, diversrfyiogthe structurallayers ofthe site. Z. The diversity of species creates additional food sources, nesting, and perching sites for wildlife 3. The site has documented use by numerous bird, mammal, and amphibians species (deer observed grazingand bedding areas, numerous species of birds, chorus frogs). 4. Open space is preserved near Blue Heron Middle School and is used by the neighborhood. A number of informal foot and bicycle trails traverse the site, especially around the perimeter of the pond. 5. The site retains seasonal stormwater, which is filtered through the emergent vegetation growing in the pond. A gravel trail to the interpretative sign has been built offof Pacific Avenue to facilitate human interaction with the site; the trail was completely overgrown with weeds in July 2002 and not passable. The project has been implemented using a phased installation process as indicated in the maintenance and monitoring schedule outlined in Table l.

Water meters, the staff gauge, and other permanent landmarks define Zone boundaries. A map of the location of the monitoring Zones is included in the Appendix (Figure I). 2.2.1 Determining Survival Rates of Trees, Shrubs, and Emergents Monitoring data sheets were used to determine plant survivorship and to record conditions of planted trees, shrubs, and emergents. These data sheets are included in the Appendix (Figures II, IfI, and IV). The individual plants were counted in each zone and compared with the numbers originally planted. Since all trees planted in specific zones were of significant size, counting individual trees was possible. Shrubs that have survived were large enough to count during the 2002 monitoring. In some species more shrubs were observed this year than last year, having survived under the weed layer, they are growing through the weeds and can now be counted. The majority of emergents were planted in or near the pond tnZone 5. Mortality and health of individuals was also evaluated and discussed. 2.2.2 Documenting Wefland Changes with Photographs Photographic monitoring provides a visual record of the restoration effort and is an excellent way to qualitatrvely document plant community changes. Six permanent photopoints were established in 1998 A map showing the photopoint locations and direction photographs were taken is included in the Appendix (Figure I). Photopoint #1 through #6 are included in the Appendix (Figures V and VI).

The final planting was in the spring of 1999; therefore, performance standards are to be evaluated during this monitoring phase (2002). Survivorship of tree and shrub species is expected to be 80% or greater after 5 years (2004)- 3.0 Results and Discussion Dixie Llewellin of Olympic Wetland Resources, lnc has been retained to collect data for this monitoring project. Fieldwork was conducted on July 8, 2002. Vegetation was planted and maintained fuom 1997 through 1999 by volunteers. Maintenance has been minimal during tle last 3 years. The dominant vegetation cover" especially in locations were the soil was disturbed, is a well-established weed population that continues to spread. Weedy species far exceed the performance standard for this project (Zone I along Cedar, Zone 2 along San Juan and upland niUslael. Portions of the site, where native soils were less disturbed, have a dominant cover of grasses, trees and shrubs here are not overgrown with weeds and are healthy (Zone 3 grassy field with evergreens, and along eastern edge ofpond). 3.1 Survivorship of Planted Species Survival rates were calculated by comparing live plants counted during the survey to the total numbers planted. Monitoring forms for each of the plant communities are included in the Appendix (Figure fI, III, and IV). 3.1.1 Forest Survival The survival rate for trees is moderate (71%). Several indMduals, especially the deciduous trees (mountain ash" big-leaf maples, vine maples, and serviceberry) are stressed due to the dry and weedy conditions. Douglas firs in the upland area of Zone 2were stressed because they were completely buried in weeds. Two spruces died this year due to a spruce aphid that is spreading and hard to control. Most trees did not survive along San Juan due to poor soils, weed competitioq and lack of irrigation. Along the pond perimeter, Pacific willow (which were present in 1998) are numerous and are beginning to form a hedge. They were stressed last year from lack of water but seem to have recovered and are up to 5' tall. Aspen and cottonwood, which were transplanted from the airport population rn 1997, are green and hardy. Most of the evergreen species (shore pine, cedar, Douglas fir, grand firs) are thriving and healthy. In the area of the interpretive sign, the Garry oak are struggling due to weed competition but are still surviving. 3.1.2 Scrub/Shrub Survival The survival rate is 360/o for shrubs when comparing the number counted to the number planted. Shrub survival varies throughout the site according to soil types and maintenance. Hear,y clay soils were brought to the surface during the pond construction and few planted species have ever survived in the northeast corner (along Cedar Street). This year a healthy crop of lupines covered the site and will eventually enrich the soil. Elderberries are starting to become established here as well. Shrubs planted Olvmpic Wetland Resources, Inc. 4 San Juan Retention Basin Wetiand Revegetation Monitoring Report Julv 2002 along San Juan have also had a very poor survival rate due to soil conditions, lack of maintenance, and the dominance of large weedy species. Several large and established dogwoods that once thrived in the previous years along the eastern edge ofthe pond died last year due to the drought conditions. 3.1.3 Emergent Survival ln the low-lying area (Zone 5) the emergent wetland dependant vegetation is healthy, recovering from last year's drought. Survival rate is high at I95yo (count is over lO0oA due to spreading populations). This plant community is totally dependant on the natural conditions associated with rainfall. Populations of bulrush, cattails, and rushes have been spreading steadily throughout the ponded areas. Perfiormance standards at this location are meet, there is well over 85%o cover by desirable species. 3.1.4 Interpretive Area The interpretive area (Zone 4) accessed via a gravel trail from Pacific Avenue has had little maintenance and consists of invasive populations of poison hemloch Canadian and bull thistle, and curly dock- The shore pines and oaks were buried under weeds and are stressed. The gravel path and interpretative sign under a kiosk of the City of Port Townsend Stormwater project, is buried in weeds 3.2 Acfion ltems Weed/mow invasive ; contract with private company if necessary Zone I and2 along San Avenue (crrrly dock and hemlock) twice a year and hemlock) twice ayearInterpretive area (cur$ Along Cedar Street (Scot'broom and Himalayan blackberry) Remove all reed annually) between Zone 2 and Zone 3 Remove and control Remove Scots eedy Species Weed invasion is a where soils were altered during construction. In many locations the growh and smothered the planted species. The weedy species constitute in some locations. Prior to the project large populations of hemlock old buildings near San Juan Avenue The disturbed soils offered fertile contrnue to spread rapidly. Hemlock can grow to 7 feet tall and easily out compete planted species. Weedy species throughout the site include tansy ragwort, Senecio jacobaea. Canadian thistle, Cirsium arvense, poison hemloch Conium maculatum, Himalayan blackberry, Rubus discolor, and curly dock, Rumex crispus. Scot's broonr, Cytisus scoparuis, and reed canarygrass, Phalaris arundinacea, extremely invasive weeds, were located in a few locations and should be removed. The city contracted the cutting and removal of weeds in the problem areas and removed a large patch of Himalayan blackberries near Pacific Avenue. Last year the city road crew mowed accessible areas in the late summer and portions of the site were cut with a weed-eater (November 2001). This work improved the overall appearance of the site but was conducted so late into the season that a seed source was well established for this year. No maintenance has been conducted rn2002. 1 2 J Oll,rnpic Wetland Resources, [nc. 5 San Juan Retention Basin Wetland Revegetation Monitoring Report existed around than |5o/o hindered Julv 2002 4.0 Summary Performance standards established in the Froggy Bottoms, San Juan Retention Basin Wetland Revegetation Monitoring- and Maintenance Plan April 1998 require that the site be dominated by a coveiof 35Yo "deskable species" with less than l5o/o weed species 3 years after final planting in the and falls below the acceptable standards.

Regular maintenance or irrigation has not been conducted on the site as outlined by the original plan. Last year's report indicated a declining plant population and declining health in all zones and vegetation layers for species planted. Figures this year indicate that some species have continued to decline. Monitoring for 20Q2 reveals a moderate success rate for trees (7lo/o), a poor success rate for shrubs (36c. ), and a good success rate for emergents (over 100% due to population spreading). Within the emergent zone, vegetation is spreading. This area is dependant on the presence of hydrology, which fluctuates over the years due to natural conditions. Standing water was absent from the pond last year and the emergent community was stressed but water has returned to the site and the vegetation has recovered. A regular maintenance schedule should be established by the City that will be implemented for specifi. f, locations and at strategic times when the weeds are young in the spring and once again in the fall. The survival goal (80%) for trees and shrubs VUIgtlg mrt by 2004 unless additional species are planted Many other project goals and objectives have been met. The species diversity has increased dramatically from a site that was once a waste area with only grasses. Vegetation layers now include trees, shrubs, and stout emergents. The site is frequented by numerous species of birds (nesting killdeer 2001), deer, and chorus frog populations. It is also a useful open space used by the neighborhood as indicated by the gravel trails throughout the site. The pond effectively retains and filters stonnwater during the wet seasons. Long-range goals for Froggy Bottoms should be evaluated to find solutions to meet prescribed performance standards and survivorship goals. Topics to be considered include replanting barren weed filled areas, defining regular maintenance schedules, and future plans for the interpretive area. I would be happy to meet with City staffto discuss the possible solutions to this restoration project. the Ohmpic Wetland Resources, Inc. 6 San Juan Retention Basin Wetland Revegetation Monitoring Report Julv 2002 Figures Appendix Monitorin g Zones and PhotoPoints Forest Monitoring Form Scrub/Shrub Monitoring Form Emergent Monitoring Form Photopoints #1, #2, and#3 Photopoint s ll4, #5 , and #6 Chronology 1997 through 2002 I.
